Picture  Digital Form Light from the object enters the camera lens Image sensor inside the camera splits the image up into millions of pixels (squares). An LCD display on the back of the camera shows you the image that the sensor is capturing—not an image of the object seen through a series of lenses (as with a conventional camera), but a redrawn, computerized version of the original object displayed on a screen The sensor measures the color and brightness of each pixel. The color and brightness are stored as binary numbers (patterns of zeros and ones) in the camera's memory card. When you connect your camera to a computer, these numbers are transmitted instantly down the wire

Digital Image Sensor Lens: Image Sensor: Semiconductor chip made of millions of tiny, light-sensitive squares arranged in a grid pattern. These squares are called pixels.  Convert incoming light rays into electricity Incoming image is converted into an outgoing pattern of digital pixels. CMOS chip captures light rays and turns them into digital signals all on the one chip. Image sensor measures how much light is arriving at each pixel. This information is turned into a number that can be stored on a memory chip inside the camera. Thus, taking a digital photograph converts the picture you see into a very long string of numbers. Each number describes one pixel in the image—how bright or dark and what color it is.

Digital Image In a television or LCD computer screen, electronic equipment switches many colored pixels on and off very quickly. Light from the screen travels out to your eyes and your brain perceives a large, moving picture. In a digital camera, exactly the opposite happens. Light from the thing you are photographing/filming zooms into the camera lens. Incoming "picture" hits the image sensor chip, which breaks it up into millions of pixels. The sensor measures the color and brightness of each pixel and stores it as a number. Your digital photograph is effectively an enormously long string of numbers describing the exact details of each pixel it contains.
